Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration device technology, specifically a filtration device for ink manufacturing. Background Technology
[0002] New types of environmentally friendly inks include two categories: benzene-free inks and water-based inks. Water-based inks, also known as water-based inks or flexographic water-based inks, are mainly made from water-soluble resins, organic pigments, solvents, and related additives through a composite grinding process. Water-based inks are particularly suitable for packaging printing products with strict hygiene requirements, such as tobacco, alcohol, food, beverages, pharmaceuticals, and children's toys.
[0003] A Chinese utility model patent (publication number: CN214551768U) discloses an environmentally friendly water-based ink filtration device for ink production, comprising a filter box. The filter box is characterized by: two support frames on its outer side, a top plate on its upper part, a stirring assembly on the top plate, and an opening in the middle; a filter barrel inside the filter box, containing a filter screen; several filter holes on the side wall of the filter barrel; a second motor below the filter barrel; and a discharge port on the bottom surface of the filter box. This utility model, by setting up a filter box and turning on the second motor, drives the filter barrel to rotate, allowing ink to enter the filter barrel and be filtered once by the filter screen. The ink in the filter barrel undergoes a second filtration through the rotating filter holes, enhancing the filtration effect of the device. The filtered ink flows into a collection box through the discharge port, preventing the ink product from containing large, undispersed particles that could lead to a decline in product quality.
[0004] However, after the device described in the above patent is used, the filtered ink tends to adhere to the inner wall and bottom of the equipment, which is difficult to scrape off completely, resulting in raw material loss. Therefore, a filtration device for ink manufacturing is proposed to overcome the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a filtration device for ink manufacturing. The first and third scrapers simultaneously scrape the outer wall of the protective shell and the inner wall of the filter box, respectively, to ensure minimal ink residue and reduce material waste. The inclined second and fourth scrapers fit tightly against the bottom surface of the filter box, effectively removing dead corner residues that are difficult to handle by traditional devices. This solves the problem that filtered ink easily adheres to the inner wall and bottom of the equipment, making it difficult to scrape off completely and causing material loss.
[0006] This utility model is achieved through the following technical solution:
[0007] This utility model relates to a filtration device for ink manufacturing, comprising a filter box and a scraping mechanism.
